Is it possible to create custom temporal operators? I want to create something like: $eventA : EventA( this afterStart[3m30s,4m] $eventB) which would be evaluated as 3m30s <= $eventA.startTimestamp - $eventB.startTimestamp <= 4m or $eventA : EventA( this during2 $eventB) where $eventB.startTimestamp <= $eventA.startTimestamp<= $eventA.endTimestamp <= $eventB.endTimestamp as well as create various others. -- View this message in context: http://drools.46999.n3.nabble.com/Fusion-Custom-Temporal-Operators-tp4023...
